The role of beta-lactamase-producing-bacteria in mixed infections

Beta-lactamase-producing bacteria (BLPB) can play an important role in polymicrobial infections. They can have a direct pathogenic impact in causing the infection as well as an indirect effect through their ability to produce the enzyme beta-lactamase. BLPB may not only survive penicillin therapy but can also, as was demonstrated in in vitro and in vivo studies, protect other penicillin-susceptible bacteria from penicillin by releasing the free enzyme into their environment. This phenomenon occurs in upper respiratory tract, skin, soft tissue, surgical and other infections. The clinical, in vitro, and in vivo evidence supporting the role of these organisms in the increased failure rate of penicillin in eradication of these infections and the implication of that increased rate on the management of infections is discussed

How sharing can contribute to more sustainable cities

\ua9 2017 by the authors. Recently, much of the literature on sharing in cities has focused on the sharing economy, in which people use online platforms to share underutilized assets in the marketplace. This view of sharing is too narrow for cities, as it neglects the myriad of ways, reasons, and scales in which citizens share in urban environments. Research presented here by the Liveable Cities team in the form of participant workshops in Lancaster and Birmingham, UK, suggests that a broader approach to understanding sharing in cities is essential. The research also highlighted tools and methods that may be used to help to identify sharing in communities. The paper ends with advice to city stakeholders, such as policymakers, urban planners, and urban designers, who are considering how to enhance sustainability in cities through sharing

Traditional family and women's condition: The reciprocal perception of Turkish and Italians

Community psychology considers gender as a central organizing category for understanding power imbalances and directing social change. The geopolitical events of these last years are heightening the contraposition between Islamic and Western countries with significant effects on ethnic prejudices, including the perception of gender roles and women’s condition. The present study focused on two different Mediterranean countries, an Islamic and Eastern one, i.e., Turkey, and a Catholic and Western one, i.e., Italy. It aimed at investigating the reciprocal perception concerning family and the women’s condition in the two states. Participants were 400 university students, both Turkish (N=199) and Italians (N=201). We performed 2 (Italian vs. Turkish) x 2 (Italy vs. Turkey) mixed ANOVAs for repeated measures testing the significance of the differences between rater countries and rated countries. Findings demonstrated an interesting “mirror effect”: Turkish and Italians perceived their home country in similar way, and similarly different from the country of comparison. Implications are discussed.

Light Emitting Diodes and Low Level Laser Light Therapy

Low level laser therapy (LLLT), including coherent and non-coherent light sources, also known as photobiomodulation, is a non-ablative treatment modality that alters cellular biochemical processes through its action on the mitochondria and by changing the cellular redox state. Treatment is delivered by exposing cells or tissue to light of low energy densities for a specific amount of time. This process has been reported to have beneficial therapeutic effects on a wide variety of conditions that benefit from alleviation of pain or inflammation, immunomodulation, and promotion of wound healing and tissue regeneration. LLLT’s use in dermatology is still considered experimental and investigational, hence it is currently used primarily as an adjunct therapy. Skepticisms mostly stem from ambiguities in its mechanism of action and the complexity of its dosimetry. For the same reasons, guidelines directing its use are not yet well established. Nonetheless, many recent studies have reported favorable outcomes achieved with LLLT in a number of indications (e.g. wound healing, hair growth, skin rejuvenation, fibrosis) with minimal adverse events
